This problem is solved by the following: when forming exterior bodies (12F, 12B), elastic stretchable members (15, 16, 19) and logo sheets (25) are attached between an inner sheet layer (12H) and an outer sheet layer (12S) to form a portion to be a stretchable region (A2) and a portion to be a non-stretchable region (A1), the logo sheets (25) comprising crepe paper on which an logo is attached and which has a thickness of 50-200 [mu]m and a density of 50-400 kg/m3; then pressurizing the elastic stretchable members (15, 16, 19) at the portion to be the non-stretchable region (A1) from inside the inner sheet layer (12H) and outside the outer sheet layer (12S), and heating the pressurized portion from only inside the inner sheet layer (12H) in order to cut the elastic stretchable members (15, 16, 19).

Description

Breeches type disposable diaper and manufacture method thereof

Technical field

The present invention relates to Breeches type disposable diaper and the manufacture method thereof possessing the display sheet being printed with pattern etc..

Background technology

Breeches type disposable diaper typically has: exterior body, and it constitutes front portion and rear body section separate or integratedly Point；With include the built-in body of absorber, it is to be installed on exterior body from front portion in the way of rear body section Inner surface, the edge, both sides of the edge, both sides of the exterior body of front portion and the exterior body of rear body section be engaged and Form side seal portion, thus form the leg opening of waist opening and pair of right and left.

In such Breeches type disposable diaper, in order to improve the fit to health, exterior body is made to be formed as having The stepped construction of multiple lamellas, and, various elastic flexible component are arranged between this lamella with elongation state, its In, the fit to health of following structure is higher: be defined as corresponding with side seal portion before and after the waist of direction scope Enclose in region or the zone line between waist area front and back, in the longitudinal direction interval and respectively with The state extended in the width direction is provided with the elongate elastic flexible component along width (referring for example to patent literary composition Offer 1).

Waist area or zone line with there is direction overlapping ranges before and after absorber, and, have within the range For built-in body being fixed on the interior outer fixing portion of exterior body.Therefore, even if there is side before and after this absorber to cross To the mode of scope, elastic flexible component is set, its Telescopic also due to the rigidity of absorber and limited.It addition, There is also such worry: absorber shrinks in the direction of the width so that wearing feeling or aesthetic property deteriorate, or occur The kink of absorber or rupture and cause absorbent properties to reduce.

Therefore, in the past, the such countermeasure of general employing: install elastic flexible component the most continuously, and Cut off fine for its most whole part overlapping with absorber, or, will at the part overlapping with absorber Elastic flexible component be fixed on exterior body and in the middle of the width one at position this elastic flexible component is cut off, The contractility being consequently formed width does not act on the non-telescoping region of absorber.For this cutting-off method, as The one of the method for not perforate on the inside and outside inner side lamella of covering elastic flexible component and outside lamella, it is known that such Method: when elastic flexible component being clipped between inner side lamella and outside lamella, inside it or outside is right Place of incision pressurization and heating, thus cut off elastic flexible component.

On the other hand, on the exterior body in non-telescoping region, the contractility of elastic flexible component works hardly, Almost without forming shrinkage creases, therefore, compared with the part being formed with shrinkage creases, the permeability of light is excellent.Cause This, make to be installed between the exterior body at this position and built-in body (with reference to patent documentation 1) with the display sheet of pattern etc. Or (with reference to patent documentation 2) between the lamella of exterior body.

Display sheet is visually confirmed to be through the constituent material of exterior body, therefore, aobvious can more clearly be visually confirmed to be On this point of showing, it is desirable to as described in patent documentation 2, display sheet is installed in the elastic flexible component of exterior body And between the lamella outside it.It addition, in this case, display sheet and elastic flexible component are adjacent, therefore, in order to The impact of the contractility of elastic flexible component is completely eliminated, it is desirable to be formed as elastic flexible component relative to showing sheet and it The lamella of inner side does not fix such display sheet dorsal part not fixed structure.

, during fabrication, for by elastic flexible component and display sheet be configured at outside lamella and inner side lamella it Between state under have display sheet region by pressurization and heating by elastic flexible component cut off situation, exist with Under such problem.

That is, in order to realize following situation: even if also being able to be assuredly shut off elastic flexible component when production line is high speed And make the cutting portion of elastic flexible component be not attached to peripheral parts, it is desirable to utilize lower than the fusing point of elastic flexible component but But the protuberance of sufficiently high temperature, pressurizes to elastic flexible component across outside lamella or inner side lamella., as Outside lamella and inner side lamella, generally uses the nonwoven with the fusing point thermoplastic resin lower than elastic flexible component as raw material Cloth, therefore, at the place of incision of elastic flexible component, may remain because outside lamella is melted melted vestige or Person offers portals, thus exists and cause the aesthetic property showing sheet to deteriorate this because these cut-out vestiges are overlapping with display sheet The worry of sample.Particularly, if display sheet is general non-woven fabrics or such thermoplastic of resin molding, the most certainly There is also such worry: melt to show that sheet is partially cut off, or offer and portal.

(display sheet)

In the non-telescoping region A1 of at least one party in front side exterior body 12F and rear side exterior body 12B, with outward The mode that the inner side of lateral plate layer 12S is adjacent has clamped display sheet 25, and this display sheet 25 has the displays such as caricature, and this shows Show that the display of sheet 25 can be seen through outside lamella 12S.

It is characterised by, as the base material of display sheet 25, uses thickness to be 50～200 μm and density is 50～400kg/m³ Crepe paper.The thickness of this crepe paper is preferably 100～150 μm, and density is preferably 100～200kg/m³.Such thickness The crepe paper of degree and density can be by setting the weight of unit are as 10g/m²Above and set crape rate and manufacture as about 10% Out.Further, density can according to the weight of unit are and THICKNESS CALCULATION out.It addition, crape rate is according to ((poplar The circumferential speed of gram drying cylinder)-(circumferential speed of take-up reel))/(circumferential speed of Flying Dutchman) × 100 (%) The value calculated.

The display being additional on display sheet 25 is not particularly limited, and can be additionally implemented for the pattern of decoration by printing etc. The functions such as (including the personage of drawing and single-point pattern), using method or use auxiliary, size show or manufacture The displays such as person or the mark display such as name of product, feature functionality.

It addition, be characterised by, in order to the contractility of excess resilient extensible member 18 shadow to display sheet 25 is completely eliminated Ringing, excess resilient extensible member 18 is not secured on the lateral surface of medial surface and the inner side lamella 12H showing sheet 25. Furthermore, it is also possible to make the medial surface of display sheet 25, excess resilient extensible member 18 and the lateral surface of inner side lamella 12H Do not fix mutually.That is, the lateral surface of display sheet 25 or the medial surface of inner side lamella 12H can pass through hot-melt adhesive It is fixed on opposed faces Deng fixing means, but excess resilient extensible member 18 is not solid by fixing means such as hot-melt adhesives Medial surface and the lateral surface of inner side lamella 12H due to display sheet 25.Thus, excess resilient extensible member 18 is independent Ground shrinks, and display sheet 25 does not shrinks.Such structure can be formed as follows: during fabrication, for bullet The position being positioned at non-telescoping region A1 in property extensible member 15,16,19 is not coated by hot-melt adhesive etc., thus makes This position is not secured to show medial surface and the lateral surface of inner side lamella 12H of sheet 25.

But, in this case, the dorsal part at display sheet 25 can form continuous print gap, therefore, shows sheet 25 Becoming the entirety floated from inner side lamella 12H, there is the unexpected gauffer of formation etc. affects the worry of aesthetic property.Therefore, Excess resilient extensible member 18 is made to be not secured to show the medial surface of sheet 25 and the lateral surface of inner side lamella 12H and will be aobvious Showing that the medial surface of sheet 25 and the lateral surface of inner side lamella 12H are joined directly also is preferred mode.Make inner side Lamella 12H is engaged in the means of display sheet 25 and is not particularly limited, but, melting if, with inner side lamella 12H Connect (particularly by the welding caused by heating during cut-out elastic flexible component 15,16,19 described later), then due to Display sheet 25 is the crepe paper on surface with fine gauffer, and therefore, the fused mass of inner side lamella 12H pastes well It is more firmly secured together on display sheet 25, is therefore preferred.It addition, inside utilizing lamella 12H In the case of welding, if the air permeability of the crepe paper for showing sheet 25 is 1～50cc/cm²Sec, especially 2～ 25cc/cm²Sec, then the fused mass of inner side lamella 12H is good, therefore especially relative to the stickiness of display sheet 25 It is preferred.

(cut-out of elastic flexible component)

Stretching region A2 and non-telescoping region A1 can be formed by following manner: glue with by hot melt to inside piece layer Connect agent etc. and be fixed with elasticity of supply extensible member 15～17,19 between the outside lamella 12S of display sheet 25 at inner surface, Only fix elastic flexible component 15,16,19 in the part being positioned at stretching region A2 by hot-melt adhesive, then exist Having in the region of display sheet 25, in the middle of width, position by pressurization and is heated elastic telescopic portion Part 15,16,19 cuts off or by pressurizeing and heating thin for the almost entirety of elastic flexible component 15,16,19 Carefully cut off, thus in stretching region A2, remain retractility, and in the A1 of non-telescoping region, eliminate retractility.

(a) of Figure 13 shows that in the middle of width, elastic flexible component 15,16,19 is cut off by position Situation, sealed roller 70 possesses pressurization part 71 on outer peripheral face, this pressurization part 71 circumference one at position have Cut off protuberance 72, and cut off protuberance 72 be heated to desired temperature, utilize sealed roller 70 and with this sealed roller 70 are opposed to the backing roll 80 that the surfaces of configuration are smooth, clamp in the way of inside piece layer 12H is in sealed roller side by Display sheet 25 and elastic flexible component 15～17,19 are arranged between the lamella 12H and outside lamella 12S of inner side and form Cut-out object, be only clipped in the position cut off between protuberance 72 and the outer peripheral face of backing roll 80 to elastic telescopic portion Part 15,16,19 carries out pressurizeing and heating and cut off.On the product implementing such processing, such as Figure 14 (a), (b) shown in, between lateral film layer 12S and inner side lamella 12H, only with the bullet of stretching region A2 Property extensible member 15,16,19 continuous print cut off after remainder remain as excess resilient extensible member 18.

It addition, (b) of Figure 13 shows, the most overall fine of elastic flexible component 15,16,19 is cut off Situation, sealed roller 70 possesses pressurization part 71 at outer peripheral face, and this pressurization part 71 has multiple cut-out protuberance 73, cuts Disconnected protuberance 73 is heated to desired temperature, utilizes sealed roller 70 and is opposed to the table of configuration with this sealed roller 70 The backing roll 80 that face is smooth, clamps in the way of inside piece layer 12H is in sealed roller side and display sheet 25 and elasticity is stretched Contracting parts 15～17,19 are arranged on the cut-out object between the lamella 12H and outside lamella 12S of inner side, only exist It is clipped in the position cut off between protuberance 73 and the outer peripheral face of backing roll 80 elastic flexible component 15,16,19 is entered Row pressurizes and heats and cut off.On the product implementing such processing, as shown in (c) of Figure 14, Between the lamella 12S and inner side lamella 12H of outside, continuous with the elastic flexible component 15,16,19 of stretching region A2 Cut-out after remainder and the discontinuous elasticity of elastic flexible component 15,16,19 with two stretching regions A2 stretch The cut off machine of contracting parts remains as excess resilient extensible member 18.

According to these methods, only heat, thus from the inner side of inner side lamella 12H to the pressurization part for cutting off Elastic flexible component 15,16,19 is cut off, and, as described above to have a certain degree of thickness and density The most a certain degree of crepe paper is as the display sheet 25 of base material as not melted thermal insulation barriers function, and heat is difficult to Being transferred to outside lamella 12S, result is, in the region with display sheet 25 of non-telescoping region A1, although can Melted vestige 22 can be had as shown in Figure 14 to residue in inner side lamella 12H as cutting off vestige, but at lateral film layer Vestige 22 is not melted on 12S, even if or have melted vestige, but melt and send out further from inner side lamella 12H Exhibition, i.e. remains unconspicuous melted vestige 22.Therefore, it is possible to suppression is because of elastic flexible component 15,16,19 Cut off the deterioration of the aesthetic property of the display sheet 25 that vestige is caused.

Further, as shown in (a), (b) of Figure 14, if only on the width of non-telescoping region A1 one at Position performs the cut-out to elastic flexible component 15,16,19, even if then having melted vestige or compression vestige etc. to cut off Vestige residues in outside lamella 12S, and its area is the least, there is the advantage that following situation is less likely to occur: because cutting off Vestige overlap etc. and be difficult to see that display sheet 25 display.Particularly, as shown in (b) of Figure 14, if non- Beyond the width central authorities of stretching region A1 perform for formed non-telescoping region A1 to elastic flexible component 15, 16, the cut-out of 19, then cut off the position of vestige beyond central authorities, it is not easy to hinders the display of display sheet 25, therefore It is preferred.As cutting off pattern, in addition to mode is formed as linearity like that as shown, it is also possible to be formed as く word Shape or the suitable shape such as shape.

About the heating-up temperature (cutting off the temperature of protuberance) for cutting off elastic flexible component 15,16,19, if energy Enough it is assuredly shut off elastic flexible component 15,16,19, suitably determines, but in order to realize following situation: Even if also being able to when production line is high speed be assuredly shut off elastic flexible component 15,16,19 and make elastic telescopic portion The cutting portion of part 15,16,19 is not attached to peripheral parts, preferably melting than elastic flexible component 15,16,19 Low but the sufficiently high temperature of point.When carrying out the cut-out of elastic flexible component 15,16,19 with such high temperature, In the case of the fusing point of lateral film layer 12S and inner side lamella 12H is less than cut-out temperature, on the lamella 12H of inner side, Melted vestige 22 or offer may be remained at the place of incision of elastic flexible component 15,16,19 portal, but It is, owing to showing the effect of heat insulation of sheet 25, to reduce the impact on lateral film layer 12S.In general, in outside The fusing point of the non-woven fabrics used in lamella 12S and inner side lamella 12H is about 160～175 DEG C, elastic flexible component 15, the fusing point of 16,19 is about 200～230 DEG C, can set heating-up temperature as 180～200 DEG C.

It addition, melt due to heating when cutting off elastic flexible component 15,16,19 at inner side lamella 12H In the case of, it is possible to this situation is positively utilized as described above, makes display sheet 25 be engaged in inner side by welding Lamella 12H.

On the other hand, owing to there is such worry: the cut-out end of elastic flexible component 15,16,19 is owing to cutting Pressurization and heating during disconnected elastic flexible component 15,16,19 and be attached to show the medial surface of sheet 25, thus cause Display sheet 25 shrinks, and therefore, it is preferred mode that at least medial surface at display sheet 25 coats remover in advance.Make For remover, can be silicon system, fluorine system, long-chain fat race etc., it is possible to be not particularly limited to use.

(between crotch side turn back part)

Preferably, mode as shown in Figure 7 and Figure 8 is such, front side exterior body 12F and rear side exterior body 12B Fixed in the following manner: outside formation the sheet material of lamella 12S between crotch the end of side to the inner side of inside piece layer 12H Turn back and form the part 20 of turning back of side between part 20, and this crotch of turning back of side between crotch and do not open.Thus, front side exterior body The gap 12i end of side between crotch between display sheet 25 and inner side lamella 12H in 12F and rear side exterior body 12B Closed by sheet material at portion, therefore reliably prevent this gap 12i side opening between crotch.Result is, the most reliably prevents Stop following situation: due to the gap 12i side opening between crotch between display sheet 25 and inner side lamella 12H, cause Aesthetic property deteriorates or the inner side lamella 12H and outside lamella 12S of exterior body 12F, 12B peel off, or in order to eliminate Retractility and the excess resilient extensible member 18 that cut off expose from opening or drop out outside from opening.If it addition, It is to make outside lamella 12S turn back to the inner side of inside piece layer 12H and form side between crotch and turn back part as which 20, then the part of turning back of outside lamella 12S will not be exposed at diaper outer surface, is caused therefore, it is possible to prevent from turning back The deterioration of aesthetic property, on the contrary, it is also possible to mode as shown in figure 11 uses such structure like that: in making formation Turn back in the sheet material of lateral plate layer 12H outside of the end of side lamella 12S laterally between crotch.

Between crotch side turn back the fixed structure of part 20 without particular limitation of, part of can being turned back in side between crotch 20 by inside and outside Fixing at fixed part 201 is fixed, it is also possible to utilize the fixing of other parts to be fixed, additionally, it is possible to It is fixed on opposed faces via hot-melt adhesive with part 20 of being turned back side between crotch as shown in Figure 7.As in fig. 8 Such with the hermetic unit that label 21 represents, it is also possible to by handss based on material welding such as heat-sealing or ultrasonic sealings Section part 20 of being turned back side between crotch seals together with the part of main body of turning back.

The outside lamella 12S of exterior body 12F and rear side exterior body 12B on front side of a sheet material by sharing is formed In the case of the lamella 12H of inner side, such mode can be formed as in the way of as shown in Figure 9 and Figure 10 like that: Utilize part and the part in outside of the inner side of the sheet material turned back in the edge of side between crotch, exterior on front side of formation respectively The inner side lamella 12H and outside lamella 12S of body 12F and rear side exterior body 12B.In such manner, outside front side The gap 12i between display sheet 25 and inner side lamella 12H in dress body 12F and rear side exterior body 12B is also between crotch The end of side is closed by sheet material, the most also reliably prevent this gap 12i side opening between crotch.

Furthermore it is also possible to mode as shown in figure 12 is formed as such mode like that: exterior body 12F on front side of formation And the sheet material of the inner side lamella 12H in rear side exterior body 12B and outside being formed the sheet material both sides of lamella 12S between crotch The end of side laterally (or, it is also possible to inner side) turn back, form side between crotch and turn back part 20.Such Under mode, in front side exterior body 12F and rear side exterior body 12B display sheet 25 and inner side lamella 12H between Gap 12i is closed by sheet material the end of side between crotch, therefore reliably prevent this gap 12i side opening between crotch.

According to above-mentioned various modes, can suitably determine to turn back the length of turning back of part 20 in side between crotch, remove Can be set as outside about 5～30mm the shortest parts, it is also possible to mode as shown in Figure 9 and Figure 10 that Sample is set as the degree identical with direction length before and after the exterior body with this part 20 of turning back.

If as it has been described above, the gap 12i between display sheet 25 and inner side lamella 12H is difficult to side opening between crotch, Display sheet 25 then can be made to extend to the end of side between the crotch of front side exterior body 12F and rear side exterior body 12B, thus It is able to ensure that display area is bigger.Therefore, it is possible to by the edge of side between the crotch of display sheet 25 and have this display sheet Between the crotch of the front side exterior body 12F and rear side exterior body 12B of 25, the separating distance 25e between the edge of side is set as About 5～30mm.

As shown in (a), (b) of Figure 14, only on the width of non-telescoping region A1, position performs use In the case of the cut-out to elastic flexible component 15,16,19 forming non-telescoping region A1, excess resilient stretches After parts 18 are only cut off by elastic flexible component 15,16,19 continuous print with stretching region A2, remainder is constituted, Although also depending on the width of non-telescoping region A1, but substantially excess resilient extensible member 18 being longer.Particularly, As shown in (b) of Figure 14, it is used for being formed non-if locating execution beyond the width central authorities of non-telescoping region A1 The cut-out to elastic flexible component 15,16,19 of stretching region A1, then with the stretching region of width side Elastic flexible component 15,16, the 19 continuous print excess resilient extensible member of A2 can remain the longest., as Fruit is provided with aforesaid part 20 of turning back, then show that the gap 12i between sheet 25 and inner side lamella 12H is difficult at crotch Between side opening, therefore, it is less that excess resilient extensible member 18 exposes such worry.

In the above example, the both sides at front side exterior body 12F and rear side exterior body 12B are both provided with side between crotch and turn back Part 20, it is also possible to only any one party arrange side between crotch turn back part 20 (also include such situation: although The both sides of front side exterior body 12F and rear side exterior body 12B have display sheet 25, but only one side has side between crotch Turn back part 20).
